Description

A driving cylinder 203 is rotatably sleeved on the bottom of the upper mounting plate 202 through a bearing, and the lower end of the driving cylinder 203 passes through the top of the grading device housing 1 and extends to the inside of the grading device housing 1;

[0033] A motor 201 is fixedly installed on the upper end surface of the upper mounting plate 202, and the lower end of the output shaft of the motor 201 passes through the top of the upper mounting plate 202 and extends to the inside of the driving cylinder 203, and is mechanically linked to the inner wall of the driving cylinder 203.
